现代Fortran语言中面向数组的特征包含两类特定的流程控制结构。我们都知道,对于标量而言,可以通过使用if,case和do产生更加紧凑的代码。对于数组而言,where、forall以及do concurrent结构可以用来简化数组表达,并能避免手动扩展表达式的麻烦。作为一般说明,这些结构都可以被命名或者嵌套。下面先简要介绍下where结构。 where结构...
Google Earth Engine(重分类和where函数) 本期我们就讲一下where函数,where函数可以把影像按照不同的类别,或者不同的范围进行计算。 例如,我们想对不同地物分类的NDVI进行不同的运算,我们就可以用where函数。 我们也顺便讲一下remap函数,这个就类似于ArcGIS中的重分类。 Where函数示例(识别水体为例) 我们通常用NDWI这...

External scripts are practical when the same code is used in many different web pages. JavaScript files have the file extension .js.To use an external script, put the name of the script file in the src (source) attribute of a <script> tag:...

The String constant pool uses aHashmapin its implementation. Each bucket of theHashmapcontains a list ofStrings with the same hash code. In earlier versions of Java, the storage area for the pool was a fixed size and could often lead to the“Could not reserve enough space for object heap...
